What is llms.txt?
llms.txt is an emerging web standard — a single Markdown file at the root of your domain that gives large language models a clean, curated overview of your site. Where a sitemap lists every URL for search-engine crawlers, llms.txt is written for AI assistants: a short summary plus a hand-picked set of your most valuable pages, each with a one-line description.
The idea, proposed at llmstxt.org, is simple: modern AI systems have limited context windows and struggle to parse cluttered HTML, navigation, and scripts. A concise, predictable file lets them understand what your site is about and which pages matter most — so they can answer questions about you accurately and cite the right URLs.
Why llms.txt matters for AI search
Search is shifting. A growing share of discovery now happens inside AI assistants — ChatGPT, Claude, Perplexity, and Google's AI Overviews — rather than the classic ten blue links. These systems summarize and recommend content directly, and they favor sources they can parse cleanly and trust.
An llms.txt file is one of the simplest ways to make your site legible to them. By spelling out your key pages and what each one covers, you reduce the chance of misattribution, increase the odds of being cited, and give AI tools a reliable entry point into your documentation, products, and articles. For docs-heavy sites and SaaS products especially, it's quickly becoming table stakes.
llms.txt vs robots.txt vs sitemap.xml
They solve different problems and work best together.
| File | Audience | Purpose | Curated? |
|---|---|---|---|
| llms.txt | AI assistants / LLMs | A concise, human-curated summary of your best pages | |
| robots.txt | Search-engine crawlers | Allow or disallow crawler access to paths | |
| sitemap.xml | Search-engine crawlers | An exhaustive machine list of every indexable URL |
The llms.txt format
The format is plain Markdown: an H1 with your site name, an optional blockquote summary, then H2 sections containing bulleted links. Each link can carry a short description after a colon.

Where to host your llms.txt
Serve the file from the root of your domain so it resolves at https://yoursite.com/llms.txt — the same convention as robots.txt. On most frameworks you just drop it into the folder that serves static assets: e.g. public/ in Next.js, Vite, and Create React App, or static/ in Hugo and SvelteKit. After deploying, visit the URL to confirm it loads as plain text.
Frequently asked questions
What is an llms.txt file?+
llms.txt is a simple Markdown file you place at the root of your domain (yoursite.com/llms.txt). It gives large language models a concise, curated map of your most important pages so they can understand and cite your site accurately.
Is this LLMs.txt generator really free?+
Yes. The generator is completely free and requires no account, sign-up, or credit card. Paste a URL, review the output, and download the file.
How does the generator create the file?+
It reads your site's sitemap.xml (falling back to homepage links), then fetches each page to pull its real title and meta description. Those are grouped into sections and assembled into a spec-compliant llms.txt — no guessing, no AI hallucinations.
Where do I put the llms.txt file?+
Upload it to the root of your domain so it's reachable at https://yoursite.com/llms.txt, exactly like robots.txt. On most frameworks you can drop it in your public/ or static folder.
Can I edit the file before downloading?+
Absolutely. The preview is fully editable — tweak the summary, reorder sections, or remove pages you don't want LLMs to prioritize, then download your final version.
Does llms.txt replace robots.txt or sitemap.xml?+
No. robots.txt controls crawler access and sitemap.xml lists every URL for search engines. llms.txt is complementary: a human-curated summary of your best content, written for AI assistants rather than crawlers.
Will llms.txt improve my SEO?+
It's aimed at AI search visibility (ChatGPT, Claude, Perplexity, Google AI Overviews) rather than traditional rankings. It helps these systems surface and attribute your content correctly, which increasingly drives qualified traffic.
